How to get character velocity by pressing button created in WIDGET HUD

Hello guys

Im have removed my android sticks from game. And want to make my main character to move by clicking Buttons made in Widget HUD.
But the problem, I cant find the way how to do it. Because you cant use widget buttons in Engine-INPUT-ACTION MAPPING.
I tried alot ways how to get velocity by pressing my created Widget HUD button. but with no ressults…
maybe you could help? what Im dong wrong in added picture?

havent tested this but you could try putting the add movement input inside a custom event and see if you can call the event instead.

I did tried as you mentioned, But character is still not moving. Maybe Im doing something wrong with custom event?I replaced Widget button with keyboard A for test only

Looks like I found information I needed in this link - YouTube
